5 biggest fights the UFC could put on today

#2. Conor McGregor vs. Nate Diaz III - UFC welterweight division

Conor McGregor remains the most prominent star MMA has ever seen.

The greatest rivalry in the history of the UFC is currently tied at 1-1. Therefore, it is an absolute no-brainer for the company to put on a trilogy bout between Conor McGregor and Nate Diaz. This fight would receive a ton of mainstream attention and make the promotion huge money.

'The Notorious' and Diaz are incredibly popular, to the point that neither man’s recent losses will diminish interest in this fight too much. If anything, they seem more evenly matched than ever, and it would be hard to pick the favorite.

You are guaranteed fireworks from the build-up to the fight in a matchup between McGregor and Diaz. It would be a real shame if we never saw the trilogy bout this rivalry deserves, and now seems like the perfect time for the pair to run it back.

#1. Israel Adesanya vs. Jon Jones - UFC heavyweight division

Is Israel Adesanya vs. Jon Jones the most significant possible fight in the UFC?

While the biggest opponent at heavyweight for Jon Jones is Francis Ngannou, the biggest fight in the promotion is Israel Adesanya. Admittedly, they are two weight classes apart, but Adesanya has hinted he could eventually compete at heavyweight.

There are so many factors that would make this bout one of the biggest the sport has ever seen. They are two of the greatest competitors and have dominated the competition in their respective divisions. They’ve also gone back-and-forth extensively on social media and don’t like one another.

A feud between two champions in a new weight class is about as big a fight as you could imagine. This hypothetical fight is a genuinely mouth-watering proposition and would easily be a mainstream success given both fighters' popularity.
